Exceptions
Exception | Condition |
---|---|
ArgumentException | path is empty or null, or path starts or ends with "/". |
TimeoutException | The operation times out. The timeout period is initialized through the ServiceBusNamespaceClientSettings class. You may need to increase the value of the OperationTimeout property to avoid this exception if the timeout value is relatively low. |
